Title: Accumulator for injection of resin
Inventor: YOSHIDA HISASHI
IPC: B29C45/82
Filed: 1985-07-16
Abstract: PURPOSE:To prevent bubbles from generating in injected molten resin by a method wherein a back pressure circuit, which throttles the return oil from an oil hydraulic cylinder for a short period of time after the finish of the injection of molten resin, is provided in the oil pressure controlling circuit of the single acting oil hydraulic cylinder to actuate a molten resin injection piston. CONSTITUTION:A back pressure circuit 22, which throttles the return oil from an oil hydraulic cylinder 15 for a short period of time after the finish of the injection of molten resin, is provided in the oil pressure controlling circuit 16 of the oil hydraulic cylinder 15. When the piston 15a of the oil hydraulic cylinder 15 reaches near its stroke end, a solenoid valve for changing over back pressure 18 is excited so as to shut off a main oil passage 19 and to supply the oil pressure developed with an oil hydraulic pump P through a throttle valve 21 in the back pressure oil passage 20 into the oil hydraulic cylinder 15. Because the back pressure is applied to an injection piston 3 for a certain short period of time after the finish of injection process, no jumping-up of the piston 3 at the finish of injection process occurs. Accordingly, the air is prevented from being sucked in the molten resin.

Title: Feedback carburetor
Inventor: MAMA SHIGEYUKI
IPC: F02M19/06
Filed: 1984-07-27
Abstract: PURPOSE:To prevent an engine from stalling because of the intake of air through a fuel intake port when the liquid level in a float chamber is inclined at the time of acceleration, deceleration, sharp turning or the like of a vehicle, by providing a fuel accumulating portion surrounding the compensatory fuel intake port of a feedback carburetor. CONSTITUTION:A solenoid valve unit 4, which performs the feedback control of the ratio of fuel to air on the basis of the action of an exhaust gas sensor provided in the float chamber 1 of a carburetor, has a valve 7 for opening and closing the compensatory fuel jet port 6 of a passage for supplying fuel 3 to a nozzle. A fuel intake port 5 is provided in the lower portion of the solenoid valve unit 4. A fuel chamber 11 open at the top is provided in such a manner that a prescribed gap is defined between the fuel intake port 5 and the fuel chamber 11. Since the fuel 3 is accumulated in the chamber 11 of enough height, the fuel intake port 5 is not exposed to air even if the level of the fuel 3 in the float chamber 1 is greatly inclined at the time of acceleration, deceleration, turning or the like of a vehicle. The air is thus prevented from being sucked in to stall an engine.

Title: Operation detector for fuel injection valve in internal combustion engine
Inventor: YAMADA AKIRA
IPC: F02M65/00
Filed: 1986-07-02
Abstract: PURPOSE:To enable direct and accurate detection of the operating condition of a fuel injection valve, by detecting vibration being produce through opening/closing operation of the fuel injection valve through an impact detecting means and deciding the operating condition of the fuel injection valve on the basis of said detection signal. CONSTITUTION:When an internal combustion engine is operating, an injection timing determining means 23 determines the output timing of injection pulses synchronous with the open-valve timing of an intake valve 20 on the basis of an output from a crank position detecting means 17. With the output timing thus determined, a generating means 25 outputs injection pulses during the injection time determined by an injection time determining means 24. Here, an impact detecting means 48 is provided to a fuel injection valve 5 so as to detect the vibration being produced by the open/ close operation of the fuel injection valve 5. Output signals from the impact detecting means 48 are fed through a signal amplifying means 49 and an operating pulse generating means 50 to an operating condition deciding means 26, and if it is decided that the fuel injection valve 5 is not functioning well, a display means 27 and a fuel pressure feed stop signal generating means 28 are functioned.

IPC: B23K9/073
Filed: 1992-05-22
Abstract: PURPOSE:To reduce the generation of spatter by detecting the instantaneous value of the output voltage interrupted through a switching element, comparing it with the set value of the output voltage and driving ON/OFF of the switching element. CONSTITUTION:An AC power source 1 is rectified by a rectifier circuit 2, made a prescribed voltage by turning on and off the switching element 3 and supplied to a welding electrode 6. An unsmoothed output voltage immediately after the switching element 3 is detected by a detector 18 for output voltage. The detected value of the voltage detector 18 is integrated by an integrating circuit 15. The output of the detector 18 and of the integrating circuit 15 are compared, and the ON/OFF of the switching element 3 is controlled. As the phase compensation circuit of an error amplifier is not required, no delay element is contained in a signal transmission system, a high-speed response is made possible against change in the output setting signal, and simultaneously a stable operation is obtained.

Title: Autotensioner
Inventor: OUCHI HIDEO
IPC: F16H7/08
Filed: 1989-06-20
Abstract: PURPOSE:To facilitate to accurately finish the elasticity of a torsion coil spring so as to conform to the design value by forming first and second straight parts extending in the tangential direction on both ends of the torsion coil spring. CONSTITUTION:First and second straight parts 39a, 39b formed on both ends of a wire material 38 for constituting a torsion coil spring 29 are elastically abutted on a first plane part 28a on a fixing member 24 side and on a second plane part 36b on an oscillating member 30 side respectively. Thereby both ends of the spring 29 are lockedly engaged with a first circumferential wall 27 fixed to the member 24, and with a second circumferential wall 34 fixed to the member 30 respectively. Consequently, the necessity to bend the wire material 38 constituting the spring 29 in a small curvature can be dispensed with. When the spring 29 is manufactured, only cold coiling of a heat-treated wire material 38 will do, and reheating of the heat-treated wire material 38 can be dispensed with. As a result, repeated heat treatment of quenching and tempering for the wire material 38 can be also dispensed with, and the finishing of the spring 29 in a dimensional accuracy as specified in the design can be relatively facilitated.

Title: Travelling device of tape-like medium
Inventor: KIDO HIDEJI
IPC: G11B15/60
Filed: 1983-08-27
Abstract: PURPOSE:To mprove the positioning accuracy of a tape width direction by constituting a tape guide of a wall member having a surface curved in the tape travelling direction, and a supporting member abutted on one end surface of the tape and regulating the position in the tape width direction. CONSTITUTION:The tape 22 contacts the curved surface 15e of the tape guide 15 and receives force pushing the tape 22 downwards because the wall member 15d constituting the curved surface 15e is inclined inside by a slight angle of about 0.3-4 deg. from the axial direction l of the guide pin 25, so that the lower end of the tape 22 is pressed to the upper surface of the supporting member 15c. Since the tape 22 contacing the curved surface 15e increases the rigidity of the width direction apparently larger than that of the tape material itself by the contact, the end surface of the tape 22 is surely regulated by the upper surface of the supporting member 15c without being curled. Consequently, the positioning accuracy in the tape width direction at the recording and reproducing time are improved.

Abstract: PURPOSE: To prevent illuminance reduction at the limited height by providing rotary paraboloid reflecting mirrors having a focal point at a light source on the upper rear, lower right and lower left of the light source, radiating parallel light forward directly from the former, and radiating parallel light forward via two plane mirrors on both wings respectively from the latter.  
     CONSTITUTION: A reflecting mirror 2 made of nearly the upper half section of a rotary paraboloid having a focal point nearly at a light source 1 is formed behind the filament 1a of the light source 1, reflecting mirrors 3, 4 made of rotary paraboloids having the focal point nearly at the position of the light source 1 are formed on the lower right and left, and the light of the light source 1 is made parallel light and is divided horizontally on the right and left. The light is reflected upward by plane mirrors 5, 6 and forward by plane mirrors 7, 8 and is projected forward through an integrated lens together with the light from the reflecting mirror 2. Even a luminaire limited in height to the utmost can increase the light beam utilization factor, obtain the prescribed brightness without increasing power consumption, and easily optimize the horizontal and vertical light distribution characteristics via the adjustment of the plane mirrors 5, 6, 7 and 8.

Title: Manufacture of semiconductor device
Inventor: ISHITANI HIROSHI
IPC: H01L21/28
Filed: 1985-07-17
Abstract: PURPOSE:To prevent crystal defects from generating in the surface of a semiconductor substrate by a method wherein a resin film and metal film are subjected to etch-back by plasma until the resist pattern is exposed equipped with a flattened surface before it is removed for the formation of a wiring. CONSTITUTION:After the formation of an insulating film 2 of SiO2 or the like on the surface of a semiconductor substrate 1, a resist pattern 3 of a 1.5mu-thick PMIPK provided with an opening 3a is formed on the insulating film 2. Next, a 1mum-thick wiring Al alloy film 4 is deposited on the resist pattern 3 and in the opening 3a. Further, a resin film 5 (polyimide) is laid by application by using a spinner or the like, with the surface virtually flattened. The resin film 5 and metal film 4 are subjected to plasma etching by using a chlorine- based gas. The etching continues until the surface of the resist pattern is exposed flat. Finally, the resist pattern 3 is immersed in a resist-swelling liquid for removal from the insulating film 2, whereafter only the metal film filling the opening 3a is retained to serve as a wiring 4a.

Title: Heat source system
Inventor: OKUDA ISAMU
IPC: F24F11/00
Filed: 1977-12-23
Abstract: PURPOSE: To provide a heat source system, in which a compressor motor is driven at a high speed and at a variable speed, through the control of an inverter that produces a higher frequency than commercial power source, so as to change refrigerating capacity of the compressor to meet with the load, whereby it is enabled to improve efficiency of operation.  
     CONSTITUTION: When operating torque Tc of compressor 3 is almost exceeds, for instance, point K 1  in the attached graph of characteristic curve, rotational speed of motor 4 is lowered by the function of a first torque controlling circuit 39. On the other hand, when compressor 3 is operated under the condition of point K 1  and shaft torque TM of motor 4 takes characteristic curve TM 2  in response to the change of speed instruction signal Vs, operating point of compressor 3 is shifted along the broken line shown in the drawing and compressor 3 is operated at point K 2  on characteristic curve TM 2  for a certain while. Subsequently, operation of compressor 3 is continued at point K 3  on the curve TM 2 , by the function of a second torque controlling circuit 40 and through stabilization of refrigerating cycle. Thus, it is prevented that operating torque becomes excessively large and thus it is enabled to stabilize the operation of compressor system.
